1. SUMMARY DESCRIPTION
The HYNIX HY27(U/S)F(08/16)1G2M series is a 128Mx8bit with spare 4Mx8 bit capacity. The device is offered in 1.8 V
Vcc Power Supply and in 3.3V Vcc Power Supply.
Its NAND cell provides the most cost-effective solution for the solid state mass storage market.
The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old
data is erased.
The device contains 1024 blocks, composed by 64 pages consisting in two NAND structures of 32 series connected
Flash cells.
A program operation allows to write the 2112-byte page in t ypical 300us and an e r ase op er a tion can be pe rf ormed in
typical 2ms on a 128K-byte(X8 device) block.
Data in the page mode can be read out at 50ns cycle time per word. The I/O pins serve as the ports for address and
data input/output as well as command input. This interf ace allows a reduced pin count an d easy migr ation towards dif-
ferent densities, without any rearrangement of footprint.
Commands, Data and Addresses are synchronously introduced using CE#, WE#, ALE and CLE input pin.
The on-chip Program/Erase Controller automates all program and erase functions including pulse repetition, where
required, and internal verification and margining of data.
The modifying can be locked using the WP# input pin.
The output pin RB# (open drain buffer) signals the status of the device during each operation. In a system with mul-
tiple memories the RB# pins can be connected all together to provide a global status signal.
Even the write-in tens ive systems can take advantage of the HY27(U/S)F(08/16)1G2M extended r eliabilit y of 100K pr o-
gram/erase cycles by providing ECC (Error Correcting Code) with real time mapping-out algorithm.
Optionally the chip could be offered with the CE# don’t care function. This option allows the direct download of the
code from the NAND Flash memory device by a microcontroller, since the CE# transitions do not stop the read opera-
tion.
The copy back function allows the optimization of defective blocks management: whe n a page progr am operat ion fails
the data can be directly programmed in another page inside the same arr ay s ection without the time consuming serial
data insertion phase.
The cache program feature allows the data insertion in the cache register while the data register is copied into the
flash array. This pipelined program operation improves the program throughput when long files are written inside the
memory.
A cache read feature is also implemented. This feature allows to dramatically improve the read throughput when con-
secutive pages have to be streamed out.
This device includes also extra features like OTP/Unique ID area, Automatic Read at Power Up, Read ID2 extension.
The HYNIX HY27(U/S)F(08/16)1G2M series is available in 48 - TSOP1 12 x 20 mm , 48 - USOP1 12 x 17 mm.

1.2 PIN DESCRIPTION
Pin Name Description
IO0-IO7
IO8-IO15(1)
DATA INPUTS/OUTPUTS
The IO pins allow to input command, address and data and to output data during read / program
operations. The inputs a r e latched on the rising edge of Write Enable (WE#). The I/O buf fer float to
High-Z when the device is deselected or the outputs are disabled.
CLE COMMAND LATCH ENABLE
This input activates the latching of the IO inputs inside the Command Register on the Rising edge of
Write Enable (WE#).
ALE ADDRESS LATCH ENABLE
This input activates the latching of the IO inputs inside the Address Register on the Rising edge of
Write Enable (WE#).
CE# CHIP ENABLE
This input controls the selection of the device. When the device is busy CE# low does not deselect
the memory.
WE# WRITE EN AB LE
This input acts as clock to latch Command, Address and Data. The IO inputs are latched on the rise
edge of WE#.
RE#
READ ENABLE
The RE# input is the serial data-out control, and when active drives the data onto the I/O bus. Data
is valid tREA after the falling edge of RE# which also increments the internal column address counter
by one.
WP# WRITE PROTECT
The WP# pin, when Low, provides an Hardware protection against undesired modify (program /
erase) operations.
RB# READY BUSY
The Ready/Busy output is an Open Drain pin that signals the state of the memory.
VCC SUPPLY VOLTAGE
The VCC supplies the power for all the operations ( Read, Write, Erase).
VSS GROUND
NC NO CONNECTION
PRE
To Enable Power On Auto Read. When PRE is a logic high, Power on Auto Read mode is enabled, and
when PRE is a logic low, Power Auto Read mode is disabled. Power On Auto Read mode is available
only on 3.3V device.
Not using POWER-ON AUTO-READ, connect it Vss or leave it N.C.
Table 2: Pin Description
NOTE:
1. For x16 version only
2. A 0.1uF capacitor should be connected between the VCC Supply Voltage pin and the VS S Ground pin to decouple
the current surges from the power s upply. The PCB track widths must be sufficient to carry the currents required
during program and erase operations.

2. BUS OPERATION
There are six standard bus operations that control the device. These are Command Input, Address Input, Data Input,
Data Output, Write Protect, and Standby.
Typically glitches less than 5 ns on Chip Enable, W rit e Enable and R ead Enabl e are igno red by the memory an d do not
affect bus o perations.
2.1 Command Input.
Command Input bus operation is used to give a command to the memory device. Command are accepted with Chip
Enable low, Command Latch Enable High, Address Latch Enable low and Read Enable High and latched on the rising
edge of Write Enable. Moreover for commands that starts a modifying operation (write/erase) the Write Protect pin
must be high. See figure 5 and table 13 for details of the timings requirements. Command codes ar e always applied on
IO7:0, disregarding the bus configuration (X8/X16).
2.2 Address Input.
Address Input bus oper ation allows the insertion of the memory address. To insert the 27 addresses(x8 device ) needed
to access the 1Gbit 4 clock cycles are needed. Addresses are accepted with Chip Enable low, Address Latch Enable
High, Command Latch Enable low and Read Enable high and latched on the ris ing edg e of Write Enable. Moreover f or
commands that starts a modify operation (write/erase) the Write Protect pin must be high. See figure 6 and table 13
for details of the timings requirements. Addresses are always applied on IO7:0, disregarding the bus configuration
(X8/X16).
2.3 Data Input.
Data Input bus operation allows to feed to the device the data to be programmed. The data insertion is serially and
timed by the Write Enable cycles. Data are accepted only with Chip Enable low, Address Latch Enable low, Command
Latch Enable low, Read Enable High, and Write Protect High and latched on the rising edge of Wr ite Enable. See figure
7 and table 13 for details of the timings requirements.
2.4 Data Output.
Data Output bus operation allows to read data from the memory array and to check the status register content, the
lock status and the ID data. Data can be serially shifted out toggling the Read Enable pin with Chip Enable low, Write
Enable High, Address Latch Enable low, and Command Latch Enable low. See figures 8,10,11 and table 13 for details
of the timings requirements.
2.5 Write Protect.
Hardware Write Protection is activated when the Write Protect pi n is low. In this condition modify operation do not
start and the content of the memory is not altered. Write Protect pin is not latched by Write Enable to ensure the pro-
tection even during the power up.
2.6 Standby.
In Standby mode the device is deselected, outputs are disabled and Power Consumption is reduced.

3. DEVICE OPERATION
3.1 Page Read.
Upon initial devi ce power up , the device de fault s to R ead mode. This oper ati on is also initi ated by writ ing 00h and 30h
to the command register along with four address cycles. In two consecutive read operations, the second one doesn’t’
need 00h command, wh ich four address cy cles and 30h command initiates that op eration. Two types of operations are
available : random read, serial page read. The random read mode is enabled when the page address is changed. The
2112 bytes (X8 device) or 1056 words (X16 device) of data within the selected page are transferred to the data regis-
ters in less than 27us(tR). The syste m co ntr oller may detect the com pletion of this data transfer (tR) by analy zing the
output of R/B pin. Once the data in a page is loaded into the data registers, they may be read out in 60ns cycle time
by sequentially pulsing RE#. The repetitive high to low transitions of the RE# clock make the device output the data
starting from the selected column address up to the last column address.
The device may output random data in a page instead of the consecutive sequential data by writing ra ndom data out-
put command.
The column address of next data, which is going to be out, may be cha nged to the address which follows r andom data
output command.
Random data output can be operated multiple times regardless of how many times it is done in a page.
3.2 Page Program.
The device is progr ammed basically by pa ge, but it does allow multiple par tial page pr ogr amming of a word or consec-
utive bytes up to 2112 (X8 device) or words up to 1056 (X16 device), in a single page program cycle. The number of
consecutive partial page programming operation within the same page without an intervening erase operation must
not exceed 4 times for main array (X8 device:1time/512byte, X16 device:1time/256word) and 4 times for spare array
(X8 device:1time/16byte ,X16 device:1time/8word).
The addressing should be done in sequential order in a block 1. A page program cycle consists of a serial data
loading period in which up to 2112bytes (X8 device) or 1056words (X16 device) of data may be loaded into the data
register, followed by a non-volatile programming period where the loaded data is programmed into the appropriate
cell.
The serial data loading period begins by inputting the Serial Data Input command (80h), followed by the four cycle
address inputs and then serial data. The words other than those to be programmed do not need to be loaded. The
device supports random data input in a page. The column address of next data, which will be entered, may be
changed to the address which follows random data input command (85h). Random data input may be opera ted multi-
ple times regardless of how many times it is done in a page.
The Page Program confirm command (10h) initiates the programming process. Writing 10h alone without previously
entering the serial data will not initiate the pr ogr am ming process . The internal write s tate contro ller automatically ex e-
cutes the algorithms and timings necessary for program and verify, thereby freeing the system controller for other
tasks. Once the progr am process starts, the R ead Status Regis ter command may be entered to read the status register.
The system controller can detect the completion of a pr ogr am cycle by monitoring the RB# output, or the Status bit (I/
O 6) of the Status Register. Only the Read Status command and Reset command are valid while programming is in
progress. When the Page Program is complete, the Write Status Bit (I/O 0) may be checked. The internal write verify
detects only errors for "1"s that are not successfully programme d to "0"s . The command r egister r ema ins in Read Sta-
tus command mode until another valid command is written to the command register. Figure 13 details the sequence.

3.3 Block Erase.
The Erase oper ation is done on a block basis. Block addr ess loading is accomplished in two cycles initiated by an Erase
Setup command (60h). Only addr ess A18 to A27 (X8) or A17 to A26 (X16) is v alid while A12 to A17 (X8) or A11 to A16
(X16) is ignored. The Erase Confirm command (D0h) following the block address loading initiates the internal erasing
process. This two-step sequence of setup f ollowed by ex ecutio n command ensur es that memory contents are not acci-
dentally erased due to external noise conditions.
At the rising edge of WE# after the erase confirm command input, the internal write controller handles erase and
erase-verify.
Once the era se process starts , the R ead Status Register command may be entered to r ead the status register. The sys-
tem controller can detect the completion of an erase by monitoring the RB# output, or the Status bit (I/O 6) of the
Status Register. Only the Read Status command and Reset command are valid while erasing is in progress. When the
erase operation is completed, the Write Status Bit (I/O 0) may be checked.
Figure 17 details the sequence.
3.4 Copy-Back Program.
The copy-back program is configured to quickly and efficiently rewrite data stored in one page without utilizing an
external memory. Since the time-consuming cycles of serial access and re-l oading cycles ar e remov ed, the system per-
formance is improved. The bene fit is especially obvious when a portion of a block is updated and the rest of the block
also need to be copied to the newly assigned free block. The operation for performing a copy-back program is a
sequential execution of page-read without serial access and copying-program with the address of destination page. A
read operation with "35h" command and the address of the source page moves the whole 2112byte (X8 device) or
1056word (X16 device) data into the internal data buffer. As soon as the device returns to Ready state, Copy Back
command (85h) with the address cycles of destination page may be written. The Program Confirm command (10h) is
required to actually beg in the programming operation. Data input cycle for modifying a por tio n or multip le distant por-
tions of the source page is allowed as shown in Figure 15.
"When there is a program-failure at Copy-Back operation, error is reported by pass/fail status. But, if
Copy-Back operations are accumu lated over time, bit e rror due to charge loss is not checked by external
error detection/correction scheme. For this reason, two bit error correction is recommended for the u se
of Copy-Back operation."
Figure 15 shows the command sequence for the copy-back operation.
3.5 Read Status Register.
The device contains a Status Register which ma y be read to find out whether rea d, progra m or erase oper ation is com-
pleted, and whether the progr am or er as e oper a tion is c omplet ed successf u lly. After writing 70h comman d to the com-
mand register, a read cycle outputs the content of the Status Register to the I/O pins on the falling edge of CE# or
RE#, whichever occurs last. This two line control allows the system to poll the progress of each device in multiple
memory connections even when RB# pins are common-wired. RE# or CE# does not need to be toggled for updated
status. Refer to table 14 for specific Status Register definitions. The command register remains in Status Read mode
until further commands are issued to it. Therefore, if the status register is read during a random read cycle, the read
command (00h) should be given before starting read cycles. See figure 9 for details of the Read Status operation.

3.6 Read ID.
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an
address input of 00h. F our read cycles sequentially output the manufactur er code (ADh), and the device code and 00 h,
4th cycle ID, respectively. The command register remains in Read ID mode until further commands are issued to it.
Figure 18 shows the operation sequence, while tables 16, 17 explain the byte meaning.
3.7 Reset.
The device offers a reset feature, executed by writing FFh to the command re gister. When the device is in Busy state
during random read, pr ogr am or er ase mode, the res et operation will abort these operations. The contents of memory
cells being altered are no longer valid, as the data will be partially programmed or erased. The command register is
cleared to wait f or the next command, and the Status R egister is clear ed to value E0h when WP# is high. If the device
is already in reset state a new reset command will not be accepted by the command register. The RB# pin transitions
to low for tRST after the Reset command is written. Refer to figure 23.
3.8 Cache Program.
Cache Program is an extension of Page Program, which is executed with 2112byte (X8 device) or 1056word (X16
device) data registers , and is available only within a block. Since the device has 1 page of cache memory, s er ial data
input may be executed while data stored in data register are programmed into memory cell. After writing the first set
of data up to 2112byte (X8 device) or 1056word (X16 device) into the selected cache registers, Cache Program com-
mand (15h) instead of actual Page Program (10h) is input to make cache registers free and to start internal program
operation. To transfer data from cache registers to data registers, the device remains in Busy state for a short period
of time (tCBSY) and has its cache registers ready for the next data-input while the internal programming gets started
with the data loaded into data registers. Read Status command (70h) may be issued to find out when cache registers
become ready by polling the Cache-Busy st atus bit (I/O 6). Pass/fail status of only the previous page is available upon
the return to Ready state. When the next set of data is input with the Cache Program command, tCBSY is affected by
the progress of pending internal programming. The programming of the cache registers is initiated only when the
pending progr am cycle is finished and the data registers are availa ble for the trans fer of data fr om cache registers. The
status bit (I/O5) for internal Ready/Busy may be polled to identify the completion of internal programming.
If the system monitors the progress of programming only with RB#, the last page of the ta rget programming sequence
must be programmed with actual Page Program command (10h). If the Cache Program command (15h) is used
instead, status bit (I/O5) must be polled to find out when the last programming is actually finished before starting
other operat ions such as read. Pass/fail status is available in two steps. I/O 1 returns with the status of the previous
page upon Ready or I/O6 status bit changing to "1", and later I/O 0 with the status of current page upon true Ready
(returning from internal programming) or I/O 5 status bit changing to "1". I/O 1 may be read together when I/O 0 is
checked. See figure 16 for more details.
NOTE : Since programming the last page does not employ caching, the program time has to be that of Page Program.
However, if the previous program cycle with the cache data has not finished, the actual program cycle of the
last page is initiated only after completion of the previous cycle, which can be expressed as the following
formula.
tPROG= Program time for the last page+ Program time for the ( last -1 )th page -
(Program command cycle time + Last page data loading time)

3.9 Cache Read
Cache read oper ation allows automa tic download of consecut ive pa ges, up to the whole device. Immedia tely afte r 1st
latency end, while user can start reading out data, device internally starts reading following page.
Start address of 1st page is at page start (A<10:0>=00h), after 1st latency time (tr) , automatic data download will
be uninterrupted. In f a ct latency time is 25us, while downlo ad of a page requir e at least 100us f or x8 device (50us fo r
x16 device).
Cache read operation command is like standard read, except for confirm code (30h for standard read, 31h for cache
read) user can check operation status using :
- RB# ( ‘0’ means latency ongoing, download not possible, ‘1’ means download of n page possible, even if device
internally is active on n+1 page
- Status register (SR<6> behave like RB#, SR<5> is ‘0’ when device is internally reading and ‘1’ when device is idle)
To exit cache read operation a cache read exit command (34h) must be issued. this command can be given any time
(both device idle and reading).
If device is active (SR<5>=0) it will go idle within 5us, while if it is not active, device itself will go busy for a time
shorter then tRBSY before becoming again idle and ready to accept any further commands.
If user arrives reading last byte/word of the memory array, then has to stop by giving a cache read exit command.
Random data output is not available in cache read.
Cache read operation must be done only block by block if system needs to avoid reading also from invalid blocks.

4. OTHER FEATURES
4.1 Data Protection.
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal
voltage detector disables all functions whenever Vcc is below about 1.1V(1.8V device), 2V(3.3V device). WP# pin pro-
vides hardware protection and is recommended to be kept at VIL during power-up and power-down. A recovery time
of minimum 10us is required before internal circuit gets ready for any command sequences as shown in Figure 24. The
two-step command sequence for program/erase provides additional software protection.
4.2 Ready/Busy.
The device has a Ready/Busy output that provides method of indicating the completion of a page program, erase,
copy-back, cache program and random read completion. The RB# pin is normally high and go es to low when the
device is busy (after a reset, read, program, erase operation). It returns to high when the internal controller has fin-
ished the operation. The pin is an open-drain driver thereby allowing two or more RB# outputs to be Or-tied. Because
pull-up resistor value is related to tr(R B#) and current drain during busy (Ibusy), an appropriate value can be obtained
with the following reference chart (Fig.25). Its value can be determined by the following guidance.
4.3 Power-On Auto-Read
The device is designed to off er a utomatic reading of the first page without command and address inp ut sequence dur-
ing power-on.
An internal voltage detector enables auto-page read functions when Vcc reaches about 1.8V. PRE pin controls activa-
tion of auto- page read function. Auto-page read function is enabled only when PRE pin is logic high state. Serial
access may be done after power-on without latency. Power-On Auto Read mode is available only on 3.3V device
(HY27UF(08/16)1G2M).

System Interface Using CE don’t care
To simplify system interface, CE may be deasserted during data loading or sequential data-reading as shown below.
So, it is possible to conn ect NAND Flash t o a microporc essor. The only function that was removed from standard NAND
Flash to make CE don’t care read operation was disabling of the automatic sequential read function.

Bad Block Management
Devices with Bad Blocks have the same quality level and the same AC and DC characteristics as devices where all the
blocks are va lid. A Bad Block does not affect the perf ormance of valid blocks because it is isolated from the bit line and
common source line by a select transi stor. The devices are supplied with all the locations inside valid blocks
erased(FFh). The Bad Block Information is written prior to shipping. An y block where the 1st Byte in the spare area of
the 1st or 2nd page(if the 1st page is Bad) does not contain FFh is a Bad Block. The Bad Block Information must be
read before any erase is attempted as the Bad Block Information may be erased. For the system to be able to recog-
nize the Bad Blocks based on the original information it is recommended to create a Bad Block table following the flow-
chart shown in Figure 28. The 1st block, which is placed on 00h block address is guaranteed to be a valid block.
Block Replacement
Over the lifetime of the device additional Bad Blocks may dev elop. In this case the block has to be replaced by copying
the data to a v alid block. These additional Bad Blocks ca n be identified as attempts to progr am or er ase them will give
errors in the Status Register.
As the failure of a page program operation does not affect the data in other pages in the same block, the block can be
replaced by re-programming the current data and copying the re st of the replaced block to an available valid block.
The Copy Back Program command can be used to copy the data to a valid block.
See the “Copy Back Program” section for more details.
Refer to Table 18 for the recommended procedure to follow if an er ror occurs during an operation.

5. APPENDIX : Extra Features
5.1 Automatic Page0 Read after Power Up
The timing diagram related to this operation is shown in Fig. 22
Due to this functionality the CPU can directly download the boot loader from the first page of the NAND flash, storing
it inside the internal cache and starting the execution after the download completed.
5.2 Addressing for program operation
Within a block, the pages must be progr ammed consecutively from LSB (least significant bit) page of the block to MSB
(most significant bit) page of the block. Random address programming is prohibited. See Fig. 27.

Application Note
1. Power-on/off Sequence
After power is on, the device starts an internal ci rcuit initialization when the power supply voltage reaches a specific
level. The device shows its internal initialization status with the Ready/Busy signal if initializati on i s on pro gr ess. Whil e
the device is initializing, the device sets internal registeries to default value and generates internal biases to operate
circuits. Typically the initializing time of 20us is required.
Power-off or power failure before write/erase operation is complete will cause a loss of data. The WP# signal helps
user to protect not only the data integrity but also device circuitry from being damaged at power-on/off by keeping
WP# at VIL during power-on/off.
For the device to operate stably, it is highly recommended to operate the device as shown Fig.35.

2. Automatic sleep mode for low power consumption
The device provides the automatic sleep function for low power consumption.
The device enters the automatic sleep mode by keeping CE# at VIH level for 10us without any additional command
input, and exits simply by lowering CE# to VIL level.
Typically, consecutive oper a t ion is executable right after deactivating the automatic sleep mode, while tCS of 2us is
required prior to following operation as shown in Fig.36.
